Scissors having separated blades and handles

Abstract

A pair of improved scissors is provided herein, which separates the blades and handles of the pair of scissors into individual parts. These parts are joined at the pivot point by a locking mechanism. By adjusting the locking mechanism, the included angle between the blades and handles of the pair of scissors can be varied easily in accordance the requirement of the application. In addition, with the present invention, the handles can also be replaced by those that are safer and more comfortable to operate. As such, the stress and burden of the user's fingers and wrist can be relieved in operating the pair of scissors.

1. A pair of scissors, comprising:
 a first blade and a second blade, each having an indented portion at a bottom end concaved from a front side to a back side, a ring flange protruding toward said front side within each said indented portion for an appropriate height, a through opening being provided within each said ring flange, threads and thread grooves being provided on the outer surfaces around the circumferences of said ring flanges; 
 a pivot axle and a fastening nut, said pivot axle threading through said through opening of said first blade, said through opening of said second blades in this order with said back sides of said first and second blades facing each other, said fastening nut being screwed to an end of said pivot axle exposed from said through opening of said second blade to Lock said first and second blades together; 
 a first pair of handles, each having a through opening at a top end, said through openings being provided to allow said ring flanges to be fitted inside and exposed for an appropriate height, said first pair of handles being joined to said first and second blades pin-joined by said pivot axle and fastening nut by having said through openings of said handles fitting over said ring flanges of said first and second blades respectively with said back sides of said handles facing said front sides of said first and second blades; and 
 a fastening cap having a cross-sectional shape of a bracket member whose inner wall has thread grooves and threads corresponding to the threads and thread grooves of said ring flange of said First blade; and 
 a fastening ring whose inner wall has thread grooves and threads corresponding to the threads and thread grooves of said ring flange of said second blade; 
 wherein said fastening cap is screwed to the exposed portion of said ring flange of said first blade to lock one of said first pair of handles to said first blade at an appropriate included angle therebetween; and said fastening ring is screwed to the exposed potion of said ring flange of said second blade to lock the other one of said first pair of handles to said second blade at an appropriate included angle. 
 
   
   
     2. The pair of scissors according to  claim 1 , wherein a middle section of said pivot axle has a polygonal cross-section; at least one of said through opening has a substantially identical polygonal aperture so as to prevent said pivot axle from spinning inside said through opening. 
   
   
     3. The pair of scissors according to  claim 1 , wherein the front surface of each indented portion is roughened appropriately; and the back surface at said top end of each said handle is appropriately roughened. 
   
   
     4. The pair of scissors according to  claim 3 , wherein the surfaces are roughened by one of the following means: forming parallel grooves, forming meshed grooves, and forming embossment. 
   
   
     5. The pair of scissors according to  claim 1 , further comprising a bearing being treaded through by said pivot axle in front of said first blade. 
   
   
     6. The pair of scissors according to  claim 1 , further comprising a washer being threaded through by said pivot axle between said second blade and said fastening nut. 
   
   
     7. The pair of scissors according to  claim 2 , wherein said polygonal shape is a rectangle. 
   
   
     8. The pair of scissors according to  claim 1 , further comprising at least a second pair of handles, each having a through opening at a top end, said through openings being provided to allow said ring flanges to be fitted inside and exposed for an appropriate height, said second pair of handles being joined to said first and second blades pin-joined by said pivot axle and fastening nut by having said through openings of said handles fitting over said ring flanges of said first and second blades respectively with said back sides of said handles facing said front sides of said first and second blades; wherein said first pair of handles are replaced by said second pair of handles.
